After making a batch of nice folded dipole elements on my diy jig, I needed to work out how to mount them and feed them with 50 Ohm coax. The feed point impedance should be 200 Ohms so I needed a 4:1 balun.
I’ve got a strange fascination with folded dipoles. Single or stacked and phased, I just can’t seem to shake the need to build one from my head. So toady I have made a simple jig to help bend up a batch of folded dipoles.
Having just purchased an Eton G3 radio I wanted to get into Short Wave Listening a bit more. I am generally interested in NAVTEX, DGPS signals and Numbers Stations but the internal G3 bar type antenna just wont cut it.
I initially tried to just throw up a length of wire, stretch it out across the garden and straight into the G3’s ext ant jack (which is a 3.5mm mono jack by the way). It kinda worked and I could hear a few more stations but it also pulled in a huge amount of noise generated by the nearby houses and electrical junk.
